Application filed June 30, 1914. Serial No. 848,199.

To all whom it may concern Be it known that 1, ALEXANDER Boo- DANFFY, a subject of the King of Hungary, and a resident of the city of New York, in

t the county of Kings and State of New York,

have invented certain new and useful lmprovements in Attachments for Cork-Cutting fvlachines, of which the following is a specification.

The present invention relates to cork cutting machines, and has reference more particularly to a feeding attachment therefor.

One of the objects of the invention is to provide a simple and etficient cork feeding 7 l5 mechanism that cooperates with the cork cutting devices, and automatically feeds the cork strips to the knives or cutters of the machine.

Another object of the invention is to make the feeding device adjustable to the size of the cork strips at hand, and also to the sizes of the corks desired.

With these and other objects in view, which will more fully appear as the nature of the invention is better understood, the

same consists in the combination, arrangement and construction of parts hereinafter fully described, pointed out in the appended claims and illustrated in the accompanying drawings, it being understood that many changes may be made in the size and proportion of the several parts and details of construction within the scope of the appended claims without departing from the spirit or sacrificing any of the advantages of the invention.

One of the many possible embodiments of the invention is illustrated in the accompanying drawings, in which Figure 1 is a side elevation, partly in section, of an attachment constructed in accordance with the present invention in position upon the cork cutting machine; Fig. 2 is a section taken on line 2-2 of Fig. 1; Fig. 3 is a front elevation thereof; Fig. 4. is a plan view of the same; Fig. 5 is a side elevation of a bracket by means of which the attachment is secured to the frame of the cork cutting machine; Fig. 6 is a sec- 50 tion taken on line 6-6 of Fig. 5; Fig. 7 is a plan view of the same; Fig. 8 is a side elevation of the main frame of the attachment; Fig. 9 is a section taken on line 9-9 of Fig. 8; Fig. 10 is a side elevation of a por- 55 tion of the work-holder; Fig. 11 is a. section taken on line 1111 of Fig. 10; Fig. 12 is a section taken on line 12-12 of Fig. 10; Fig. 13 is a plan view of the device shown in Fig. 10; Fig. 14 is a side elevation of a detail of the main frame of the attachment; Fig. 15 is a section taken on line 15-15 of Fig. 1%; Fig. 16 is a section taken on line 16-l6 of Fig. 14; Fig. 17 is a side elevation of a portion of the feeding means; Fig.

In the drawings only so much of the cork cutting machine has been shown as is neces sary to understand the operation of the attachment forming the subject matter of the present application for Letters Patent.

Referring now more particularly to the drawings, the numeral 30 indicates a portion of the supporting frame of the cork cutting machine, including a horizontal table section 31, in which is provided a longitudinal slot 32. Upon this table section is adjustably mounted a bracket 33, the horizon tal portion of the latter resting upon the table section 31, and being attached thereto by means of screw bolts 34: which engage a 90 clamping plate 35, that bears against the underface of said table section. The bolts 34 extend through the slot 32 in said table section and allow thus of an adjustment of the bracket and the parts carried thereby relative to the cutter of the machine. In the vertical portion of the bracket is formed a longitudinal slot 36, through which extend set screws 37, engaging screw threaded holes 38 in the main frame of the attachment, said main frame comprising a vertically extend ing transverse plate 39, with which is, preferably, cast integral an annular member 40, that embraces the supporting frame 30. This annular member is provided with a peripheral groove 41 for a purpose hereinafter to be described. The vertical plate 39 of the main frame of the attachment supports a vertical gage plate 42, that extends trans versely of the supporting frame 30, and is 110 provided withears 43, which restkupon shoulders 44 on the plate 39. One of these cars is provided with a longitudinal slot 45,

ably secured to the main frame of the attachment. Upon the gage plate is furthermore formed a tubular extension 47, that is disposed in a notch 48 in the bracket 33, and serves a purpose hereinafter to be described. A set screw 49, engaging the main frame of the attachment and the bracket 38, serves for vertically adjusting, after loosening the screws37, the attachment relative to the supporting frame 30 of the machine. A projection 12 upon the gage plate is provided with a slot. Through this slot extends a set screw 100 that attaches adjustably to the gage plate a horizontal-work support 101. Upon the gage plate is furthermore formed a transverse tubular pro ection 50,'in which is oscillatably disposed the pivot pin 51 of an arm 52, that carries a grooved idler-roller 53,which is held by means of a spring 54 upon the upper surface of the cork strip, and the weight of which tends to keep the cork strip in proper engagement with the feeding device of the apparatus. A stop screw 55, engaging the arm 52 and bearing against the gage plate 42, limits the downward motion of the idler-roller.

Over the annular member 40 is drawn a ring 56, said ring bearing against the plate 39 and against stop screws 57 upon said annular member. This ring is rotatably mounted upon said annular member and has pivotally attached thereto at 58, 58 a plurality of spring pressed pawls 59, which are adapted to-mesh with the teeth of a ratchet ring 60, that is also rotatably mounted upon the annular member 40. l/Vith this ratchet ring is made integral a feeding ring 61, and with this latter ring are connected by pins 62,0r otherwise, a series of feeding rings 63, all of which are drawn over the annular member 40. The feeding rings and also the ratchet ring are kept in position upon the annularmember by a flange 6 1, the latter being held in place by screws 65, or similar means, which engage with washers 66, that bear-against the flange 64 and the annular member 4 0,the screws being screwed into the said annular member. Withinthe groove 41 in said annular member are held a plurality of springs 67, that are attached by pins 68, or otherwise, to the said annular member and bear against the ratchet ring 60 and the feeding ring 61, thereby holding the said ratchet ring and the feeding rings connected therewith in position when the spring pressed pawls move back to their normal positions under the action of a spring 69, that is attached to the ring 56 and to an arm 70, the latter being rigidly fastened to the annular-member 40. The-feeding rings are Uprovidedwith peripheral sharp corrugations scribed, in the direction of the arrow denoted by the character A (Fig. 1). i

In the flange 64 is formed an aperture 72 in registering position with the tubular extension 47 upon the gage plate 42. -Within this aperture is held a ring-shaped presser foot 73, that is carried by an arm 74:, the latter beingpivotedat 75 to the flange 6 1 and caused to project by a spring 76 through the aperture 72 into contact with the cork-strip resting upon the support 101 and upon the feeding rings. The cutter 77 of the machine reciprocates in alinement with the presser foot 73, the corks blocked from the strips being caused to move through the tubular extension t7into a receptacle (not shown).

The-means for actuating-the feedingrings comprises a tapered cam 78, that is fixedly held by means of a set screw 79 upon a shaft 80, which is journaled in bearings 81, the latter being formed uponthe supporting frame 30. Rotation is imparted to the shaft 80 from a'driving shaft 82, which carries for this purpose a bevel gear 83, in mesh with a similar gear 8 1, that is mounted upon a shaft 85, the latter being journaled in a bearing 86. The connection between the shafts 80 and S5is made by a universal joint 87, which may be of any suitable construction, the one shown in the drawings being disclosed for purposes of illustration only. This joint comprises a cup-shaped member 88, that is attached to or made integral with the shaft 80 and carries rotatably a pin 89, to which is pivoted at the forkshaped end 91 of the shaft 85. The cam 78 coperates with an anti-friction roller 92, that is mounted upon an arm98, the latter being attached by screws 94, or otherwise, to the ring 56.

In mounting the attachment uponthe cork cutting machine, care is to be taken that the aperture 72 in the flange 64 should be in registering position with the cutter 77. To bring these parts in proper alinement, the screws 37 are somewhat loosened'and the set screw 49 rotated in one or other other direction until the parts occupy their proper positions, after which the screws 37 are properly tightened.

The operation of this device is as follows: First of all the gage plate and work support mustbe adjusted accordingto the thickness of the cork strips to be operated upon. The stop screw 55 is then set to permit the idler-roller 53 to-rest upon the cork strips, the adjustment being made obviously according to the height of the said cork strips, care being taken, -however,that the cutter 77 should not strike the idler-roller in case there are no cork strips upon the Work support. The tapered cam 7 8. is then shifted longitudinally upon the shaft 80 and placed in position according to the required stroke of the arm 93 upon the ring 56. This stroke, obviously, must correspond to the diameter of the corks to be cut, or in other words the larger the diameter of the corks to be out, the larger must be the stroke, and vice versa. It is to be observed that the relation between the cork cutter actuating means and the shaft 80 must be such that the feeding of the cork strip, that isto say the raising of the arm 93 must take place when the cutter is moving outward, that is away from the work. The cork strips are placed upon the work support and forced by hand within the reach of the feeding rings and the idler-roller. The shaft 80, in its rotation, raises by the intermediary of the cam 78 the arm 93 upon the ring 56 and thereby causes the latter to swing in the direction of the arrow indicated by the character A (Fig. 1), whereby the ratchet ring is caused by the pawls 59 to swing a corresponding distance, carrying with it the feeding rings, which, in turn, cause the cork strip to advance toward the cutting means of the machine. The presser foot 7 3 prevents a backward movement of the cork strip when the ring 56 and its pawls are swung back to their normal, initial positions by the spring 69 in the further rotation of the shaft 80. The said presser. foot holds on the other hand the cork strip fixed in position during the cutting operation. These operations are continued until the cork strips are used up, it being obvious that the cork strips are continually caused to follow one another by being placed manually upon the work support.

What I claim is 1. In a feeding device for cork cutting machines, the combination with a cutter,

of a stationary frame in operative relation each stop of said ring, said cam being shiftable longitudinally upon said shaft for varying the stroke of said first mentioned means.

2. In a feeding device for cork cutting machines, the combination with a cutter, of a stationary frame in operative relation thereto, a feeding ring rotatably disposed upon said frame for advancing cork strips toward said cutter, a ratchet ring connected with said feeding ring, a ring-shaped member oscillatably mounted upon said frame, spring pressed pawls upon said ring-shaped member in engagement with said ratchet ring, a rotary shaft, a tapered cam carried by said shaft, means actuated by said cam for imparting an intermittent motion in one direction to said ring-shaped member and thus to said feeding ring, and means for causing said ring-shaped member to return to its initial position during each stop of said feeding ring, said cam being shiftable longitudinally upon said shaft for varying the stroke of said ring-shaped member.
